Agreed, I could believe everything else from this leak, it's "possible", but the Tyrion betrayal theory just makes no sense at all...The only reason this could happen is if he believe Danaerys is getting as mad as Aerys...and I can't see a Danaerys in love with Jon Snow turning to a mad queen....plus Tyrion's beloved brother comes to help Danaerys and Jon, so really...I think the chances of a Tyrion betrayal are close to zero (or it's part of a trick to fool Cersei...)...
